The Iron Horse Regional Trail runs through Danville. It was first a railroad that is now converted to a 80-foot (24 m) wide corridor of bike and hike trails as well as controlled intersections. Extending from Dublin to Concord, the trail passes through Danville. Walkers, bikers, skaters, and joggers usually find the Trail a source of outdoor recreation and exercise. Furthermore, the Trail is relatively isolated from the heavy traffic on the main roads, so it is a relatively safe path to travel on. The trail is also close to all the major bookstores, shops, cafes, and restaurants in Danville, so those who are doing a long trip often stop in Danville to eat or drink. The town ranked number one in the nation in a recent forecast done by Pinpoint Demographics for the highest per capita spending on clothing. The towns citizens are forecasted to spend more than $2,000 per capita on clothing.
